Explore semiconductor photodetector technology in this comprehensive lecture from Oxford's Michael B Johnston, examining both established and emerging innovations in light-to-electrical signal conversion. Delve into how silicon technologies have revolutionized visible light detection in everyday devices like mobile phone cameras and solar panels, while learning about Group III-V alloys' role in infrared photon collection. Discover cutting-edge developments in two novel semiconductor systems: nanostructured semiconductors for accessing underutilized electromagnetic spectrum regions and thin film perovskite semiconductors for efficient multi-junction solar cells. Learn about the development of compact detectors for far infrared (terahertz frequency) light using Group III-V semiconductor nanowires, and understand the evolution and challenges of vapor deposition techniques in creating efficient planar heterojunction solar cells based on metal halide perovskites.
